fix regression test failures with Git 3.30.5 / 2.38.1 or later installed The fix for CVE-2022-39253 in Git made our regression tests fail since creating submodules from local clones is no longer allowed by default. Add an override to our invocations of "git submodule add", the same which was added to Git's regression test suite as part of their fix. This CVE doesn't otherwise affect us. We do not implement submodules. Our use of them in regression tests exists only to ensure that Got does not freak out when it sees one. Precisely because automated support for nested repositories and/or working copies (as in Git Submodules, or Subversion Externals, etc.) have been an endless source of security problems in other systems. sudden test failures pointed out by naddy@

use test(1) -eq and -ne to compare integers, and reduce quoting This brings the rest of the regression test scripts in line with patch.sh.

use POSIX [s1 = s2] syntax instead of [s1 == s2]; patch by Ryo ONODERA

fix expected output of test_tree_submodule_of_same_repo for packed repos

switch function declarations from Korn shell to Bourne/POSIX shell syntax ok stsp

add a -q option to tests for quiet output and use it for 'make regress' Previous default output remains when test cases are run individually. ok tracey

add submodule tests ok semarie

set the executable bit on tree.sh

spacing

make got tree work on current branch and add tests for this use case ok stsp
